Referring to FIG. 9, a washing mode WM of the washing machine 1 may be displayed on the display window 52 a of the display 52 (1000). That is, in response to the power-on of the washing machine 1, a washing mode list, which is previously stored, may be displayed one by one on the display window 52 a.

A user may search for a washing mode included in the washing mode list by rotating the inputter 51 a, which is implemented in a form of a jog dial, clockwise CW or counterclockwise CCW.

The inputter 51 may receive a washing mode select command from a user (1010). That is, the user may select a washing mode to perform washing while searching for a washing mode, and the storage 800 may store the washing mode selected by the user (1020). The washing machine 1 may perform washing on laundry in the washing mode, which selected by the user, under the control of the controller 600.

The controller 600 may identify the number of times of washings for each washing mode selected by a user during a predetermined number of times of washings based on the number of selection times of the washing mode stored in the storage 800. That is, when the user performs 10 times of washings using the washing machine 1 for a certain period, the controller 600 may identify the frequency of selection of the selected washing mode for each washing, and thus the controller 600 may identify a washing mode that is the most frequently selected for 10 times of washings. The number of times of washing, which is pre-determined to identify the frequency of selection of the washing mode, may vary according to the setting.

The controller 600 may identify whether a washing mode, which is selected the most frequently by a user during the predetermined number of times of washings, is plural or not (1030).

As a result of the identification that the number of the most frequently selected washing mode is not plural, the controller 600 may allow the washing mode, which is selected the most frequently by a user, to be displayed on a first screen of the display window 52 a (1040).

Referring to FIG. 10, in a case in which ‘wool/lingerie’ mode is selected four times, ‘standard washing’ mode is selected three times, ‘towel’ mode is selected once, and ‘baby clothes’ mode is selected two times during the washing machine 1 performs 10 times of washings, ‘wool/lingerie’ mode is identified as a washing mode that is the most frequently selected by a user.

Therefore, the controller 600 may allow ‘wool/lingerie’ mode, which is the most frequently selected for 10 times of washing that is predetermined, to be displayed on the first screen of the display window 52 a. In response to the power-on of the washing machine 1, the controller 600 may allow ‘wool/lingerie’ mode to be displayed first on the first screen.

That is, in a general case, a washing mode is displayed on the display window 52 a according to the washing mode list that is previously set and stored, as illustrated in FIG. 9. However, according to the washing machine and the control method thereof according to an embodiment, the controller 600 may identify a washing mode that is frequently selected by a user and then allow the corresponding washing mode to be displayed first on the display window 52 a. Accordingly, it is possible to increase user convenience by preferentially displaying the washing mode that has a high usage frequency according to a user's washing machine usage pattern.

Meanwhile, a user may search for a washing mode list displayed on the display window 52 a by rotating the inputter 51 a implemented in a form of a jog dial clockwise or counterclockwise. On the display window 52 a, ‘wool/lingerie’ mode with the highest usage frequency may be displayed on the first screen, and other washing modes may be displayed in a predetermined order as shown in FIG. 9 according to washing mode search of the user.

Referring to FIG. 8A again, as a result of the identification of the controller 600 that the most frequently selected washing mode is plural, the controller 600 may allow a washing mode, which is the last selected by a user among the plurality of washing modes, to be displayed on the first screen of the display window 52 a (1050).

Referring to FIG. 10, in a case in which ‘wool/lingerie’ mode and ‘bedding’ mode are selected four times and ‘towel’ mode and ‘baby clothes’ mode are selected once during the washing machine 1 performs 10 times of washings, ‘wool/lingerie’ mode and ‘bedding’ mode are identified as a washing mode that is the most frequently selected by a user.

Therefore, the controller 600 may allow ‘bedding’ mode, which is the last selected by a user between ‘wool/lingerie’ mode and ‘bedding’ mode which are the most frequently selected by a user for 10 times of washing that is predetermined, to be displayed on the first screen of the display window 52 a. The controller 600 may allow ‘wool/lingerie’ mode to be displayed after ‘bedding’ mode. In response to the power-on of the washing machine 1, the controller 600 may allow ‘bedding’ mode to be displayed first on the first screen.

According to the washing machine and the control method thereof according to an embodiment, the controller 600 may identify a washing mode that is frequently selected by a user and a washing mode that is the last selected by a user, and then allow the corresponding washing mode to be displayed first on the display window 52 a. Accordingly, it is possible to increase user convenience by preferentially displaying the washing mode that has a high usage frequency and the washing mode that is the last used by a user according to a user's washing machine usage pattern.

Meanwhile, a user may search for a washing mode list displayed on the display window 52 a by rotating the inputter 51 a implemented in a form of a jog dial clockwise or counterclockwise. On the display window 52 a, ‘bedding’ mode that has the highest usage frequency and that is the last selected by a user may be displayed on the first screen and ‘wool/lingerie’ mode may be displayed on a next screen, and other washing modes may be displayed in a predetermined order as shown in FIG. 9 according to the washing mode search of the user.

Referring to FIG. 8B, the inputter 51 may receive a selection of a washing mode from a user (1100), and the display 52 may display a washing option for the selected washing mode (1110).

As illustrated in FIG. 12, as for the washing machine 1, a washing option may be basically set for each washing mode and stored in the storage 800. In response to user's selection of washing mode, the washing machine 1 may perform washing on laundry with a washing option corresponding to the selected washing mode unless the user changes the washing option.

The inputter 51 may receive a washing option change command for the selected washing mode from a user (1120).

That is, the user may change the washing option while washing is performed according to the selected washing mode, and thus the washing may be performed according to the changed option and data regarding the washing option changed by the user may be stored in the storage 800.

Based on the number of times of receiving the washing option change command stored in the storage 800, the controller 600 may identify the number of times of changing the washing option for each the washing mode selected by the user.

The controller 600 may identify whether or not the washing option change command for the washing mode is received a predetermined number of times (1130), and as a result of the identification that the washing option is changed the predetermined number of times, the controller 600 may store the changed washing option command in the storage 800 (1140). In this case, the predetermined number of times that is used for the controller 600 to identify the number of the washing option change command may be three times, but this may vary according to the setting.

In response to the user's selection of the washing mode in which the washing option is changed the predetermined number of times, the controller 600 may allow the changed washing option to be displayed on the display 52 (1150), and the controller 600 may allow the washing machine 1 to perform the washing mode with the changed washing option (1160).

As mentioned above, in a case in which a washing option is set for each washing mode as illustrated in FIG. 12, when a user selects ‘wool/lingerie’ mode, the washing is performed in the corresponding washing option such as ‘temperature 30° C.’, ‘rinse 3 times’, and ‘spin level 4’.

However, after selecting ‘wool/lingerie’ mode, the user may change ‘spin level’ from level 4 to level 2, and as a result of identification of the controller 600 that the number of times in which a user changes ‘spin level’ in ‘wool/lingerie’ mode from level 4 to level 2 is three times, the controller 600 may store the changed ‘spin level’ in the storage 800.

In addition, when the user selects ‘wool/lingerie’ mode during the washing, the changed washing option ‘spin level 2’ may be displayed on the display 52, and the washing machine 1 may perform washing in ‘wool/lingerie’ mode with ‘spin level 2’

As mentioned above, according to the washing machine and the control method according to an embodiment, the controller 600 may identify a washing option, which is frequently changed and used by a user, allow the corresponding washing option to be displayed on the display 52 and perform the washing with the corresponding washing option, thereby increasing the user convenience.

Referring to FIG. 19, for example, in a state in which the washing mode currently displayed on the display window 52 a is ‘bedding’, when a user inputs a search command in the clockwise direction CW through the inputter 51 a, ‘boil washing’ mode next to ‘bedding’ mode may be displayed on the display window 52 a. On the other hand, when a user inputs a search command in the counterclockwise direction CCW through the inputter 51 a, ‘wool/lingerie’ mode, which is the previous washing mode of ‘bedding’ mode, may be displayed on the display window 52 a.

Meanwhile, the controller (600) may preferentially determine a display order of the washing mode list displayed on the display window 52 a among the plurality of washing mode lists in proportion to the number of times of the washing mode selected by a user (1360).

The controller 600 may store the number of times of the washing mode selected by the user among the washing mode list and data regarding the selected washing mode in the storage 800 (1370), and the controller 600 may allow a washing mode that is frequently selected by a user to be displayed first on the display window 52 a. That is, the controller 600 may display the washing mode on the display window 52 a according to the display order of the washing mode list determined based on the number of times selected by the user (1380).

In response to the power on of the washing machine, the controller 600 may allow the washing mode to be displayed based on the previously determined display order of the washing mode list, and in response to the number of the washing modes having the same number of selection times being plural, the controller 600 may allow a washing mode, which is the last selected, to be preferentially displayed among the plurality of washing modes.

As the frequency selected by the user for the plurality of washing modes is changed, the order of washing modes preferentially displayed on the display window 52 a may be changed.

Referring to FIG. 18B, the communication circuitry 700 may download a new washing mode list from a server connected to a network (1400). That is, in addition to the washing modes previously stored in the washing machine 1, the communication circuitry 700 may download the new washing mode list.

The controller 600 may identify whether a new washing mode downloaded by the communication circuitry 700 is plural or not (1410), and as a result of identification that the new washing mode is not plural, the controller 600 may allow the downloaded new washing mode to be displayed at the end of the washing mode list displayed on the display window 52 a (1420).

In addition, as a result of identification that the downloaded new washing mode is plural, the controller 600 may allow the plurality of new washing modes to be displayed at the end of the list of washing modes displayed in order of download on the display window 52 a (1430).

As illustrated in FIG. 20, when the communication circuitry 700 downloads new washing mode 01 to new washing mode 04 in order, the new washing mode 01 to the new washing mode 04 may be displayed at the end of the washing mode list, which is previously displayed on the display window 52 a, in the order of download.

In response to inputting a search command in the clockwise CW direction by a user through the inputter 51 a, the new washing mode 01 to the new washing mode 04 may be displayed in order on the display window 52 a, and in response to inputting a search command in the counterclockwise CCW direction by a user through the inputter 51 a, the new washing mode 01 to the new washing mode 04 may be displayed in reverse order of the download on the display window 52 a that is the last downloaded new washing mode is displayed first.

That is, the washing machine 1 may download a new washing mode from the server according to the changing weather or washing trend, and the washing machine 1 may have the effect of expanding the washing method in various ways.

Referring to FIG. 18C, a user may input a user-set washing mode through the inputter 51 (1400), and the storage 800 may store the received user-set washing mode (1410).

That is, in addition to the washing mode and washing option preset in the washing machine 1, a user may input a user-set washing mode for directly setting the washing mode and washing option.

The controller 600 may identify whether a user-set washing mode input from a user is plural or not (1420), and as a result of identification that the user-set washing mode is not plural, the controller 600 may allow the user set washing mode to be displayed prior to the washing mode list displayed on the display window 52 a (1430). In this case, in response to the power-on of the washing machine 1, the display window 52 a may display a user-set washing mode input from the user.

In addition, as a result of the identification of the controller 600 that the user-set washing mode is plural, the controller 600 may allow the received user-set washing mode to be sequentially displayed from a user-set washing mode that is the last received (1440). In this case, in response to the power-on of the washing machine 1, the display window 52 a may display a user-set washing mode, which is the last input from a user, among the plurality of use-set washing modes input from the user.

As illustrated in FIG. 21, when user-set washing mode 01 to user-set washing mode 03 are input in order, the user-set washing mode 01 to the user-set washing mode 03 may be displayed from the user-set washing mode 03, which is the last input, prior to the washing mode list, which is previously displayed on the display window 52 a.

In response to inputting the search command in the clockwise CW direction by a user through the inputter 51 a, the plurality of user-set washing modes may be displayed on the display window 52 a in reverse order of input, which is the last input user-set washing mode is displayed first. In response to inputting the search command in the counterclockwise CCW direction by a user through the inputter 51 a, the plurality of user-set washing modes may be displayed on the display window 52 a in order of input, which is the first input user-set washing mode is displayed first.
